The 333 Triplexer is based on the work of K6KV as presented in the June 2010 QST Magazine article "HF Yagi Triplexer Especially for ARRL Field Day".

Applications range from Field Day, to Emergencies, to Contesting, to DXpeditions. The Triplexer effectively makes one tower and a triband yagi into 3-towers and 3-yagis, while adding only a 3X5X7 inch aluminum box, weighing less than 2 pounds to your equipment list. Works well with Trap Dipoles and Verticals too.

No adjustments required. Just place in-line between transceivers, Bandpass Filters, and antenna and you are ready to go.
